Identification of genomic regions influencing the response of yield and its components to elevated CO_2 will be useful for understanding the genetics of active response to changed CO_2 environment and developing higher yiel.

Positive loci,effect increasing loci,effect decreasing loci and non environmental loci were selected from the 931 marker loci surveyed in the 15 parental lines and their correlation with yield and yield components were analyzed.

The correlated responses of yield and yield components from the correlative and path coefficient analysis of Ganxin688 cultivated in the Poyang Lake Region of Jiangxi Province as double-season late rice showed that the direct and net effects of the number of the panicles per hectare on the yield were the maximum,while those of the number of grains per panicle closely took the second place.

In this paper,in order to explore the fit cultural techniques,the yield and yield components characteristics of Yongyou 6 and Boyou 253(CK) were studied.

Biological characters, yield components and grain filling characteristic were analyzed in four types of e-hybrids.

Based on the systematically measuring and generalizing the soil fertility conditions,yield component factor and yield spatial distribution of soybean 3 750 kg·hm~(-2)in different years in Xinjang Altay area,this paper presents the corresponding condition and high-efficient cultivation technique for soybean 3 750 kg·hm~(-2)in this area.
